Omron NX-ECC202 | Omron | NX-series EtherCAT Coupler Unit

Description

The NX-ECC202 is an EtherCAT Coupler Unit from the NX-series, designed to act as the primary interface between an EtherCAT network master and the distributed NX-series I/O modules. This unit facilitates high-speed, deterministic data exchange, supporting up to 63 connectable NX Units on a single slave node. Utilizing the 100BASE-TX (IEEE 802.3) physical layer with a 100 Mbps baud rate, the NX-ECC202 ensures seamless synchronization and communication within complex machine control architectures. The device is intended for panel mounting and requires integration into an EtherCAT network managed by a compatible master controller.

Technical Specifications

Installation Guidelines

• Mounting: Mount the unit inside an industrial control panel. Ensure adequate spacing around the device for ventilation.
• Grounding: To ensure signal integrity and electrical safety, connect the functional ground terminal to a common ground point with a resistance of 100 Ohm or less.
• Network Wiring: Use shielded twisted-pair (STP) Category 5e or higher cables for 100BASE-TX EtherCAT connections to mitigate electromagnetic interference.
• Topology: The network topology must comply with the configuration and capabilities of the designated EtherCAT master controller.
